IMPROVEMENT IN CHOPPING-MACHINES.

The Schedule referred to in these Letters Patent and making part of thelam..

To all whom 'it may concern:

Be it known that I, EMANUEL NEWCOMER, of Columbia., in the county ofLancaster and State of Penn Sylvania, have invented certain Improvementsin Chopping-Machines, ot' which the following is a'specification.

The first part of my invention relates to the combined lever-and-pawlarrangement to turn-a series of' springs out of the way, as well as toregulate the power of their action on thev choppers, the construction ofelbowed chopper-supports with their cushioned springsnpports and socketends, and binding or adjustingscrews, together with the belt-tigbtener,and the manner of revolving the block in the arrangement of the severalparts, of otherwise common machines for mincing meat.

The accompanying drawing illustrates the several parts, in which--lFigurel is a side elevation.

Figure 2, a rear elevation to show the elbowed ends of the,chopper-holders, side wheels, springs elevated with the lever and pawl.

Figure 3 illustrates one of' the four chopper-holders with the stern andchopper down.

Figure 4 illustrates the saine when elevated and sustained by thecross-rod U.

-A A are two vertical posts, between which the choppers, springs, andlifting-drum'have their bearings.

B is the raised bed or bottom of the machine.

C is an ordinary revolving block.-

D a tin or metallic case or ring fitted on the block B. Between the twothere is a groove or flange for a belt, cord, orits equivalent, markedE.

F I1", are two driving-wheels,- like balance-wheels, one on each side,with a handle, f, on the shaft that supports the drum H with its littersh.

-Gr is a belt-pulley between wheel F and frame A.

It is a belt-tightener, and made adjustable by a setscrew, r. Thebearings for the drum-shaft are between uprights A and W, with afollower or box to secure it.

The choppers O have a square stein, N, passing through a socket end ofthe support, in which the same is held and made adjustable by aset-screw, n..

This supporting-head K is horizontal, with an inclined or elbowterminus, J, rounded and thickened at the bend and perforated for afulcrum-rod, which sustains four such chopper-holders, as shown by Iig.2.

This fulerum-rod has' a head at one end and a screw for a nut on theother; so also tbe rod that holds the spring bar T.

This spring bar has four dat springs, S, secured with screwbolts, forreplacing in case of any one breaking.

These springs rest on gum-elastic pads m on a raised lug, M, near thesocket end of, the support K.

To operate the spring bar T with the springs S a rack, Q, is attached tothe upright A, into which a pawl, I?, catches.

This pawl is connected with a lever, L, for turning the spring bar; saidpawl is provided with aspring.

Ther-eis also a rod, U, across the machine to provide a means forlockingthe ends J when the choppers are to be removed -i'rom the block;when turned up, as shown by tig. 4, the rod Uis passed behind the lowerends of J and laid in the hooks on the inner sides of the uprights A A',which thus hold them up securely.

The operation has no special novelty, as revolving blocks surmonntedwith metallic rims, and choppers actuated by litters and aided bysprings, are not new, but are seen in various patents differentlyconstructed and arranged, however. I

The novelty consists in the construction andarrangement of the severalparts. Therefore,

NVhat I claim, and desire to secure by Letters Patent, is

l. The arrangement of the iixed rack Q, the pawl I), with its fulcrum onthe lever L, in combination with the .spring bar T and springs S for thepurpose,

both of turning them out of the way and for adjusting the pressure onthe choppers, in the manner' shown and specified.

2. The arrangement of the stem M with its gumelastic pad m on thesoclget-shait K, in combination with the chopper-stem N, set-screw n,and end J, to-

gether with the lifters hand drum H with the pulley G,st1aptightener It,all constructed and operating substantially in the manner and for thepurpose described.
